Descrição de Produto

The most commonly used materials for the seat ring and seat of soft-sealed butterfly valves are EPDM, nitrile rubber, and polytetrafluoroethylene plastic. The soft-sealed butterfly valve with EPDM rubber seat material usually works in a working environment with a pressure less than 2.5Mpa and a temperature of -50~80ºC. Applicable media include salts, acids, metal coating solutions, and water. , Wet chlorine, etc. 

The soft-sealed butterfly valve with nitrile rubber as the seat material usually works in a working environment with a pressure less than 2.5Mpa and a temperature of -10~90ºC. The applicable media include water, oil, waste liquid, etc. The soft-sealed butterfly valve with polytetrafluoroethylene as the seat material can be used in an environment where the pressure is less than or equal to 1.6Mpa and the temperature is -196~200ºC. 

1. The valve body is small and light, easy to install, disassemble and repair, and can be installed at any position in the pipeline.

2. The whole valve has a simple structure and is very compact, with small operating torque, and can be opened and closed by rotating 90 degrees.

3. It has good flow regulation performance.

4. The seal can be replaced, the sealing performance is good, and the two-way sealing can be achieved.

5. The butterfly plate can be sprayed with a coating layer, such as nylon rubber or polytetrafluoroethylene, according to the needs of users.

6. Flange connection and wafer connection can be designed according to requirements.

7. According to the requirements of the working conditions, the soft-sealed butterfly valve can be driven manually, electrically or pneumatically.

The butterfly valve body is a sturdy, rigid piece of metal that covers the internal parts. The seat covers the inner edge of the valve's walls and is the primary sealing agent. When the butterfly valve is closed, the disc lodges against the seat and the butterfly valve closes.

Wafer valves are a great choice for many applications because they are lightweight, compact, and are easy to install. They don't need expensive exotic materials, and they are also much more cost-efficient than other butterfly valves. However, the body and valve linings are often prone to wear and tear, which makes maintenance much more difficult. In order to properly maintain a wafer butterfly valve, you must shut down the entire pipeline.

When the butterfly valve is closed, the wafer aligns with the direction of flow. When the wrench is rotated back to its original position, the valve opens. As the commodity passes through the valve, the wafer is pushed into position. This prevents the commodity from getting stuck in the valve. The valve can be used in many different ways.
